Some fiossils have stored carbon while alive and then died with a lot of carbon in them.
The release of carbon from limestone reservoirs into the atmosphere is most often accomplished through the decay and erosion of limestone deposits in canyons.
CO2 AKA carbon dioxide.
Alveolus
diffusion
Go away
carbon dioxide
The Process of gas exchange is called Respiration
Carbon is in all living things, therefore when living things die, the carbon gets recycled back into the environment. The reservoirs of carbon are in the atmosphere as carbon dioxide, in fossil fuels, peat, durable organic material, etc.
The gases that are exchanged are oxygen and carbon dioxide.
During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
Carbon Sink
Limestone.
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
The gases that are exchanged are oxygen and carbon dioxide.
Carbon dioxide
CARBON RESERVOIRS - petroleum and coal OXYGEN RESERVOIRS - ice, human body and water
